修改指点杆速度，敏捷度：
[root@T7 ~]# echo 250 > /sys/devices/platform/i8042/serio1/serio2/sensitivity [root@T7 ~]# echo 250 > /sys/devices/platform/i8042/serio1/serio2/speed [root@T7 ~]# echo 97 > /sys/devices/platform/i8042/serio1/serio2/speed [root@T7 ~]# echo 200 > /sys/devices/platform/i8042/serio1/serio2/sensitivity
改不改的，好像没什么变化捏。

有变化有变化，而且效果和明显。
我最后选了，sensitivity 245， speed 220 取值范围在0-255 之间。
手指头终于没那么累了。 目前方法是使用一个脚本手动设置，过两天改成自动配置。

我很久以前，实现的一份配置。目前仍然生效，但是与speed无关。
/home/tong [tong@T7] [9:35] > cat /etc/X11/xorg.conf.d/20-trackpoint.conf Section "InputClass" Identifier "Trackpoint Wheel Emulation" MatchProduct "TPPS/2 IBM TrackPoint" MatchDevicePath "/dev/input/event*" Option "EmulateWheel" "true" Option "EmulateWheelButton" "2" Option "Emulate3Buttons" "false" Option "XAxisMapping" "7 6" Option "YAxisMapping" "5 4" EndSection
新增一份speed的配置。
/home/tong [tong@T7] [9:38] > sudo libinput-list-devices

-------------------------------------- update @ 2017-07-19 ---------------------------------------
前文的配置方式，以及如下的配置方式，都无法对sensitivity的配置生效：开机之后sensitivity的值始终为默认的200.
> cat /etc/udev/rules.d/30-trackpoint.rules ACTION=="add", SUBSYSTEM=="input", ATTR{name}=="TPPS/2 IBM TrackPoint", ATTR{device/speed}="213" ACTION=="add", SUBSYSTEM=="input", ATTR{name}=="TPPS/2 IBM TrackPoint", ATTR{device/sensitivity}="244"
--------------------------------------- update @ 2018-03-05 -------------------------------------------
既然rules.d不能设置sensitivity, 那么我们就换一招设置sensitivity, 把speed留给rules.d进行设置.
┬─[tong@T7:~]─[11:43:23 AM] ╰─>$ cat /etc/udev/rules.d/71-trackpoint.rules ACTION=="add", SUBSYSTEM=="input", ATTR{name}=="TPPS/2 IBM TrackPoint", ATTR{device/speed}="213"
使用hwdb设置sensitivity, 参考https://wiki.archlinux.org/index.php/TrackPoint
cp /usr/lib/udev/hwdb.d/70-pointingstick.hwdb /etc/udev/hwdb.d/71-pointingstick-local.hwdb
修改该文件的中内容如下:
┬─[tong@T7:~]─[11:46:30 AM] ╰─>$ tail -n 5 /etc/udev/hwdb.d/71-pointingstick-local.hwdb # Lenovo Thinkpad *60 series evdev:name:TPPS/2 IBM TrackPoint:dmi:bvn*:bvr*:bd*:svnLENOVO:pn*:pvrThinkPad??60:* evdev:name:TPPS/2 IBM TrackPoint:dmi:bvn*:bvr*:bd*:svnLENOVO:pn*:pvrThinkPad??60?:* POINTINGSTICK_SENSITIVITY=244 POINTINGSTICK_CONST_ACCEL=1.0
然后, 执行命令:
$ systemd-hwdb update
至此, 重启系统, speed和sensitivity就都能成功开机自动设置了.
不过, 我的蓝牙鼠的速度怎么好像也变快了呢? 难道是幻觉???
所幸, 鼠标速率调整起来比较容易. 调到满意就好了.
